如何使用鼠标滚轮在opencv python中放大和缩小图像？

import cv2

def mouse_callback(event, x, y, flags, param):
    global scale

    if event == cv2.EVENT_MOUSEWHEEL:
        if flags > 0:
            scale += 0.1  # 放大图像
        else:
            scale -= 0.1  # 缩小图像

        # 重新调整图像大小
        resized_image = cv2.resize(image, None, fx=scale, fy=scale, interpolation=cv2.INTER_LINEAR)
        cv2.imshow("Image", resized_image)

image = cv2.imread("image.jpg")
cv2.namedWindow("Image")
cv2.setMouseCallback("Image", mouse_callback)

scale = 1.0  # 初始缩放比例

while True:
    cv2.imshow("Image", image)
    key = cv2.waitKey(1) & 0xFF
    if key == 27:  # 按下"Esc"键退出
        break

cv2.destroyAllWindows()
